Crazy Cloud Rolls Over Northern Lake Michigan [VIDEO]

It's not a roll that you'd eat with dinner, it's a roll CLOUD. Ever heard of that before? We haven't!

A roll cloud is caused by a wave of rising air. As the air rises, it cools and condenses into a cloud, then peaks shortly after, sinks, and dries back out to invisibility. Does that make sense? If not, that's fine. I don't understand it, either. Which is why I'm not a meteorologist. But it's cool to look at!

Nick Nerbonne was at Sleeping Bear Dunes National Lakeshore when he caught it on camera. Pretty sweet video!
